This invention relates to an oiling device for springs of vehicles, and is particularly adaptable to oiling leaf springs used in the construction of automobiles.

The primary object of the invention is to v provide a casing for enclosing the spring having a suitable reservoir in association with the casing for containing ar lubricant which is supplied to the spring by the boundlo ing of the automobile, during -its passage over the road.

Further objects of the invention are to provide. a spring oiler of the character referred to that is strong, compact and durable,

u thoroughly reliable for its intended purpose,

very simple in its method of assembly, and comparatively inexpensive to manufacture and install on all standard types of automobiles. gg With the fo-regoing and other objects in i view, the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompany` ing drawings, wherein is disclosed an embodiment `of the invention, but it is to be understood that changes, variations, and modiiications, may be resorted to without departing from the spirit of the claim hereto ap* pended.

In the drawings wherein like reference` characters denote corresponding parts throughout the several views :4-

Figure 1 is a side elevation partly in section of the spring suspension of an automobile, showing-the spring oiler of the present invention applied thereto,

Fig. 2 is a detailed longitudinal vertical section through the spring oiler,

Fig. 3 is a detailed vertical section through the oiler taken substantially on the line 3&3

of Fig. 2.

In the drawings wherein for the purpose of Y illustration is shown the preferred embodi- 45 ment ofrour invention, 4 indicates one side rail of a. chassis frame of an automobile. To the one end of the chassis frame 4 is pivoted one end of the longitudinal leaf spring 5 on the pin 6. The other end of the spring V5 is pivotally connected to the lower ends of VA said the links 7 by the pin 8, and the upper ends I u of the linksare pivoted to an intermediate portion ofthe side rail 4 by the pin 9. A transverse aXleA l0 is anchoredtoithe middle of the leafspring 5 in anyconventional manner. f Y here *arer two spring oilers indicated generally at l1, `l2 disposed one to `each `side of the `axle l0 andV terminating attheir outer ends adjacent the opposite ends of the spring. 95 Each spring oiler A, B is formedlin the same manner and itis believed that-adescripti'on of the one, will clearly teachy the construction of theother. i i

Each oiler consists of a substantially U- 05 shaped top sectionsll anda bottom section 22 interitting within the top section, the sections wheniin 'interiittingrelatiom conformably fitting the top, bottom and sides of one half 'of the spring. The U-shaped 7b bottom section 22 has the free edges offits sides- 14, l5 tapering upwardly and rearwardly so as to accommodate the configuration of the spring, the'isaidfspring'being thicker at the center thanit is at its ends.` e VIThetop section llhasfits sidestapering 1n the same manner andthe sides `12,13 of top section overlap the sides`l4, lo'f the bottom section'v as suggestedfin Fig. Across the inner r.face the top or coverV section, at fthe deepfend thereof is a strip of felt lfor. absorbing lubrication, and also closing the space between the top of the spring' andthe crown of the cover or top section. Y 85 There is likewise a strip .o'ff felt 18 in Vthe crown at'theother endofithe coverlfor theV same purpose asfthe strip 17.`

Across the inner face of the crown of the bottom section atthe deep lend of said bottom 9i) section'risa felt strip 23 which servesthe same purpose as, andv isinualinement with the felta strip 17 There is also ia feltfstrip 24 aerossthe .innerface of the crown of the bottom section attheshallowe'st Vend 95 thereof, which is in alinement withthe feit strip 18 yon thecover section.V

Intermediate the ends of the oiler, the-b'ottom wall of the bottom member' For! section bf y `the oiler is fformedwith a Well125, andthe 150 of. the crown 164335.

bottom Wall of the bottom section opposite the well is'provided with suitable openings for a purpose hereinafter made manifest.

Arranged within the bottom section and extending across the bottom wall thereof, is a strip of felt or other suitable absorbing material M for disposition between the bottom wall of said bottom section and the bottom of the spring.

One or more wicks lV extend upwardly from the well, through the openings in said bottom wall to merge with the felt pad M, whereby oil is drawn from the well by capillary attraction into the oiler to be absorbed by the felt pad M.

A nozzle fitting 26 is anchored to one of the side walls of the well 25 for the purpose of introducing lubricant into the well. This nozzle is preferably provided with a Check valve outwardly to prevent the lubricant escaping from t-he well.

Secured to the outer face of the crown of the bottom section 22 adjacent one end thereof, is a yoke E27 having lateral outstanding hooks 28, 29 at its ends which are in alinement with the hooks 20, 2l of the yoke 19 on the top of the device. Coil springs 30, 31 have eyelets 32 on their opposite ends to engage with the lateral hooks on the sides of the cover and bottom sections for holding said sections together about the spring 5.

The outer end of each of the devices is held in place by the clip and its bolts shown generally atll.

Thus, it will be seen that we have provided a very simple detachable spring oiler having means at its opposite ends to prevent the escape of lubrication, and each section of the oiler is preferably formed of a rigid metal so as to be strong and durable.

rlhe present embodiment of the invention has been disclosed n considerable detail merely for the purpose of exempliiication, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the claim or the requirements of the prior art.

Having thus described our invention, what we claim as new is:-

In a spring oiler, a casing open at its opposite ends adapted to receive a leaf spring extending therethrough, said casing comprising a top section, a bottom section, said sections being substantially channel-shaped in cross section, the sides ofone of said section being arranged in overlapping relation with respect to the sides of the other of said sectlon, means at the ends of the section to prevent the escape of lubricants, said bottom section formed with a lubricant well having communication with the interior of the bottom section, a lubricant absorbing pad arranged in the bottom section for substantially the full length of said section, wicks extending from the well into said bot-tom section to merge with said absorbing pad, a clamp overlapping the sections at one end, and co-acting retractile means on the other end of the sections for holding said sections together.

In testimony whereof wefaiiix our signatures.

EARL E. CRONENWETH. CHARLES G. HAMER.
